In May 2009, O'Reilly Radar did an interview with Hansson, who described himself as part of Google's search user interface group, and head of a project on search microformat data. OK, that's essentially data -- like product reviews, product prices and information -- that Webmasters can provide in a specific format so that Google can improve search results when you want to find, say, a printer with certain features and good reviews in a specific price range.

SearchEngineLand thinks it's probably a general update on things Google is doing in search.

I hope there is some substance to this announcement. If not, Google is going to lose some of the excitement cachet that they are building up. The last couple events have been borderline exciting and search isn't exactly an iPod event.
